What is the purpose of the ulimit command in Linux?

The ulimit command in Linux is used to set and display resource limits for user processes. It allows system administrators to control and adjust the system resources that can be used by user processes.

The functions of the ulimit command include the following aspects:

1. ulimit is a command in Unix-like operating systems that sets or reports the resource limits for a user’s shell session.
2. Limit maximum user processes.
3. Set limits on the resources a user can use.
4. set a limit on resources

It is important to note that the ulimit command only affects user processes in the current session and does not have any limits for the superuser (root). To permanently change resource limits, you need to edit the /etc/security/limits.conf file and add the necessary configurations.
